I like buying slots.. But at the same time, I would like to remove additional slots

Simply asking to allow us to remove purchased marking slots we no longer want. It's one thing not to have a marking in the slot, but I would at least like the option altogether to remove it, for the sake of slimming slots down and making it neat. Imagine having 13+ slots, and only 10 active markings, what's the point? Why not just remove those slots?

* No I don't want the SB back, I don't mind the one-time purchase
* I just want to be able to have temporary slots that I'm free to delete when I no longer want/need them
