Force Stem Down attribute doesn't stay active

Just a feedback, in my piano part bass staff, I set many note stems to point down (so that it won’t clash with the treble staff above) by setting “Force Stem Down” attribute. But when I copy these bars to another location in the same score, the attribute is reset to “Stemp Up”. I think this also happens when the score is automatically formatted.

My workaround is simply to re-do the “Force Stem Down” for each affected note. If there’s any better solution, please let me know!
