Retrieve the multi-value columns along with normal columns using 1

Is there a ways I can retrieve the multi-value columns (ex. BusinessLine, 
ChannelRole etc) from the profiles (ex. organizationobject profile) along 
with the normal columns (ex. Org_Name, Division etc.) in one API call. 
Currently we retrieve columns that are not multi-valued and loop through
the 
data and query again for each organization to retrieve the multi-value 
columns.

Code: 
public void PopulatePartnerDetailsByAll(DataTable dtPartnerDetails,
DataSet 
dsBusinessData, DataSet dsChannelRole)
        {
            dtPartnerDetails.Columns.Add(new 
DataColumn("BusinesslineDescription"));
            dtPartnerDetails.Columns.Add(new 
DataColumn("ChannelRoleDescription"));
            try
            {
                int intRowCount = dtPartnerDetails.Rows.Count - 1;
                for (int intRowIndex = intRowCount; intRowIndex >= 0; 
intRowIndex--)
                {
                    object[] multiValueBusinessline = 
dlPartnerLocator.GetMultipleValue(dtPartnerDetails.Rows[intRowIndex][0].ToString(),
"BusinessLine");
                    object[] multiValueChannelRole = 
dlPartnerLocator.GetMultipleValue(dtPartnerDetails.Rows[intRowIndex][0].ToString(),
"ChannelRole");
                    if (multiValueBusinessline == null && 
multiValueChannelRole == null)
                    {
                        
dtPartnerDetails.Rows[intRowIndex]["BusinesslineDescription"] = "";
                        
dtPartnerDetails.Rows[intRowIndex]["ChannelRoleDescription"] = "";
                    }
                    else if (multiValueBusinessline != null && 
multiValueChannelRole == null)
                    {
                        
dtPartnerDetails.Rows[intRowIndex]["ChannelRoleDescription"] = "";
                        string strBusiness = null;
                        DataRow[] drDescription;
                        for (int intMultivalueIndex = 0;
intMultivalueIndex 
<= multiValueBusinessline.Length - 1; intMultivalueIndex++)
                        {
                            drDescription = 
dsBusinessData.Tables[0].Select("BusinessLineID ='" + 
multiValueBusinessline[intMultivalueIndex].ToString() + "'");
                            if (drDescription.Length > 0)
                            strBusiness = 
drDescription[0]["BusinessLineName"] + "<br>" + strBusiness;
                            else
                            throw new
