Collective token separators

Can I suppress the commas separating the components of a collective token?
Specifically, {@staffLabelsShort@} gives me S,A,T,B and I want SATB.


No, I’m afraid not. Perhaps you could repurpose a different token from Project Info to provide the required result (i.e. you enter “SATB” into one of the fields in Project Info and then use the corresponding token).
