Unmerge sectors that arent connected?

[NinjaLiquidator]

Hello, I want to know if there is a quick function for unmerging sectors that arent connected together by any line (I mean those type of sectors where you have one island and second island and they belong to one sector). It would save me a lot of time, cause when I have merged sectors and I split the big room, the secs stay merged and I have to manually draw a shape over every sector I want to separate...

Go to "Make Sector" mode and click a part of the non-continuous sector to disconnect it from the sector.

Works, thanks!
