[pmwiki-users] how to pass values to edit template?

[SteP]

Is there a way to pass values to an edit template?

What I have in mind is something like (I made up the syntax), say that 
EditTemplate includes

field:{$$Value}

then n=NewPage?action=edit?template=Group.EditTemplate?field=This would 
open NewPage in edit mode with

field:This

I'm not attached to the above syntax, I'm just looking for a simple way to 
expand values in edit templates, if there's a way.

TIA,
