SharePoint 2010 SPD Workflow copy list item to new list and designate the content type -

i have functioning spd workflow copies list item list list b when item in list marked approved.

my challenge list b has 3 content types chose from. how designate content type in list b use when copying. have listbox user gets choose kind of tool being loaded. tools have required calibration dates , other tool specific items therefore different content types.

i don't think can specify content type copy list item - should default default content type.

what i'd instead have workflow create list item in list b, populating fields values current item. can set content type id process doesn't accept variable, use if/then block each tool type runs if listbox value selected.

hope helps!
