Adding a split shifts the taskbar and background settings of all the splits after it. Is there a way to prevent this or correct it without reconfiguring everything?

example vertical splits:
Starting with solid background red green blue:
r|g|b

Add new split is made to the left of r:
?|r|b|g

Results in backgrounds and taskbars shifted this way:
r|g|b|!

The xml is almost there but needs a virtualization at "Monitor1_Splits" so that the splits can be re-ordered easily. Is there another way?
