Guitar capo question

Hi guys,

I work with a mixed group and frequently will have orchestra parts, vocal parts, guitar, bass guitar and keys. Often I need to capo the guitar, but not the bass and keys who may be just playing from the chord symbols. The workaround as described doesn’t seem to affect the chord symbol on the alternate part. For instance, key of F, system-wide chord symbols showing F major on a particular beat. When I change the guitar staff to key of D major (capo 3), the chord symbol does not change. If I try to change it on that staff, it changes system-wide. Any other suggestions? Hmmm, what if I change to a transposing instrument?

UPDATE - If make the player a transposing instrument, in this case alto sax, the chord symbols transpose.
