Select Specific Stash Tab To Turn Premium

Hey there,
So recently I've bought a bunch of tabs.

I usually number my tabs in a crescent fashion and keep the unlisted tabs first and listed ones later so I can better orient myself.
Thing is, one of the non premium tabs that got added (I think it was from the first blood pack) was bought after the 6 premium pack ones, and was then numbered 12.

I tried to buy a premium tab upgrade to convert it into premium so I could change the name/number but the one that was automatically converted was my number 4.
Now I can't change it to match the sequence and its bugging the hell out of me that it goes 1, 2, 3, 12, ( <- non premium ! premium -> ) 5, 6, etc.

I also really wanted to keep at least 4 non premium tabs for my own stuff and if I was to convert the 12 to premium just to change the number to 4, it wouldnt give me enough space for my own storage and I'd just waste a premium tab with perma unlisted stuff... which also feels really bad...

So what gives? Is there a way to force an upgrade into the tab that I want or am I stuck with this silly order?

Respectfully,
An OCD cursed exile.

Also, when I bought the last bundle of 6 premiums, no tabs got added and instead six of my remove-only tabs from BPL got upgraded to permanent instead, which means I didn't get much space anyway since they were already partially full.

You guys should really look into the tab transactions, cause in the end I was left feeling scammed.

I can guarantee you this will be the last time you will get any purchases from me.
