Hi @RVSLee, actually you have these possibilities:
A.
just flip the stem of the tied thirds:
B.
Or, leaving the stems up, mitigate the distances just moving the chords to the left instead of the grace notes to the right, as you seemed to have found out:
C.
You certainly can also have independent spacing of grace notes:
