Opening a member for edit/browse

I have the following PDM User-Defined Option:

      PT    STRSEU SRCFILE(SRCOBJ/QPROTOSRC) SRCMBR(&N) TYPE(&T)

It allows me to type 'PT' in the selection area on any RPG program list and
have it open a member
with the same name in the file QPROTOSRC. It helps me because I can access
the prototypes
in our system without jumping to a separate list to find what I want to
open. I can be looking at the
list with Member  MyLib/QRPGLESRC(A) and   by typing PT can open
SRCOBJ/QRPGLESRC(A)
without looking at a list from SRCOBJ/QRPGLESRC.

Is there any way I can set up a user action in WDSC that will provide this
function, I do I just have
to look mess with longer lists that include the prototypes?
