how to indicate a capo in Tabledit?

Howdy good people.

I am trying to tab a simple version of "Rights of Man." It is traditionally played in Em, and it works well in DAd with a capo at the first fret.

How do I indicate a capo in Tabledit? I could tab it out so that I indicate fret 1 for the open string with the capo, but the tradition in dulcimer tab is to indicate fret numbers as though there were no capo except for the open strings, which are referred to as 0. Is there a way to do this?

I appreciate any help you can offer. Mille grazie.
