Grouping individual targets eg Leo Triplets

[astrobrandx]

Is there a way to have a group label for targets in a target list which may be imaged together.  For example I have added M65, M66 and NGC 3628 separately in a target list but together they are commonly known as Leo Triple or Triplets and are often imaged together with a suitable set up.  Another example would be M81 and M82 which are often imaged together.
