possibility of UD1 parent-member consolidation by time

Dears, 

I need move one base member under another parent in UD1 dimensions, the problem is that member should be consolidated till specific time period and then should be consolidated under another parent. There is no option like "percent consolidation" with time frame on UD1 dimensions. Could anyone have any solution for described problem?

Before:

U1#A(parent)
 U1#A001(base) consolidated till proper month in 2026
 U1#A002(base)

After:

U1#B(parent)
 U1#A001(base) consolidated after proper month in 2026
 U1#B001(base)
