powershell get-aduser with two seperate fileds into on csv export

hello

is there any way i can use get-aduser to export two seperate ad fileds into one colume on csv export

basicaly i have description field: 1234, and Deptartment field with  "054321 - Human resources".  i need to export both fileds from get-aduser and dump into csv with one colume which would look like 1234.54321  ( i also want to remove 0 from dept.)

thx
