Yes, you'd need to add a user profile field and set it as required (i.e Required at registration...etc) then in your postbit template place this where needed.
Right under this
HTML Code:
<if condition="$post['usertitle']"><div class="smallfont">$post[usertitle]</div></if>
Add this (where X is the field number)
HTML Code:
<if condition="$post['fieldX']"><div class="smallfont">MS Office Version: $post[fieldX]</div></if>
