FM13 - Rolling subs (editor)

I know it is not for senior competitions (only amateur), but it would be great if SI included the possibility for these rules into the next edition of the FM editor. Rules like these would be a welcome addition for people who are activating the lower leagues.

Also at present the substitution rules are selected from a list, whereas it would be better if we could enter the number of substitutes manually, and have a checkbox for rolling subs.

I understand if this cannot be included seeing as we are now in June and you are probably already well into working on new features. Hopefully you are improving the editor and that this can be implemented into improvements that you are making.
