[Calc]Is there possible to sort merged cell with format?

I want to short my cell including merged ones but i can’t short with format. I wonder is it possible? i mean, can patch, feature or something make it possible?
Is there a any feature like “autosorting” (alphabetical) when i type something on the cells? If yes, i can able to merge after automatically shorted.
aaaaa|| fsfdgsdfgd || hhfgdhdfg|
bbbbb|| ffffffggggg ||aaaaaaaa|
cccc c|| Column B Column C|| ← Merged
ddddd || Column B || Column C|

Thank you
