I didn’t know what you meant for a capo chart. Paged Dr. Google and what I found was a chart that showed a table of notes for rows and capo positions for columns. If that is what you are talking about, then yes you can use one for mandolin. Notes are notes and chords are chords, regardless of the (typical) instrument.
With that said… with a short amount of work, you’d be able to figure that stuff out. Basically once you understand how to count up the scale, everything else should fall into place. For instance, you probably know how to play open chords for G, C and D. Let’s say you are doing a song in A. If you know that A is two half steps higher than a G, just put a capo on 2, play a G and voila! An A chord. The other common chords that are in use in A are D and E. Automagically you get those from C and D shapes when capoed at 2. I would expect Ben’s theory classes would give you what you need to never look at a capo chart again.
One other thing I would encourage… there are a ton of great open chords and variants. I play mando with worship some and I love the open chords. They are easy to play and sound lovely. If you are interested in those, we could do a different thread on those.
