dimension multiple holes with the same diameter

Hello,

I would like to dimension several holes such that one I can place one dimension with a leader saying, e.g., "20-3 HOLES". I can add a relation making several circles of equal diameter such that when I dimension one, all the circles have the same dimension, but the dimension text with the leader never indicates that that dimension pertains to multiple holes.

Thanks In Advance!
