Reverse Prefix in rules

[just-kirb]

Check ([ ] -> [x]) all that apply, then describe the issue below:

• I have searched the tracker for similar issues (including closed ones)
• I have provided a detailed example for how this feature should work
• I have provided a use case for this feature, e.g. short description/share link of a game you're making and how you'd use the feature in that game, other things you've tried, edge cases, etc. (if applicable)

There should be a feature to have a prefix in a rule to reverse the rule priority order where up to down and left to right rule application within one rule becomes down to up and right to left.
Example:
So lets say you want to move the Xs exactly one tile to the left with a rule without invoking movement directions, since it requires going through all the rules, it can be done easily like this:
once left [X|]->[|X]
?(?x)xxx?? ->?(x?)xxx??
?x(?x)xx?? ->?x(x?)xx??
?xx(?x)x??->?xx(x?)x??
?xxx(?x)??->?xxx(x?)??
??xxxx?? becomes ?xxxx???
however, making a similar rule
once right [X|]->[|X]
doesn't work, as the leftmost x gets applied first regardless of what happens, causing the other xs to be deleted
??(xx)xx?? ->??(?x)xx??
???(xx)x?? ->???(?x)x??
????(xx)??->????(?x)??
?????(x?)?->?????(?x)?
??xxxx?? becomes ??????x?

once right [X| no X]->[|X]
doesn't work either as it only runs the rightmost X once
??xxx(x?)?->??xxx(?x)?
??xxxx?? becomes ??xxx?x?
with a reverse prefix however, the rule runs the check from right to left and down to up
once reverse right [X| no X]->[|X]
??xxx(x?)? ->??xxx(?x)?
??xx(x?)x? -> ??xx(?x)x?
??x(x?)xx? -> ??x(?x)xx?
??(x?)xxx? -> ??(?x)xxx?
??xxxx?? becomes ???xxxx?
Reason to implement the feature:
As mentioned, it allows an easier way to move objects without directional actions that requires finishing the rules , and allows a solution for some cases where the order of applying 1 rule becomes an issue.

Not aware of this as a problem, need a repro case.
Is this during rule application, or movement phase?

[just-kirb]

during rule application

[david-pfx]

And the code that triggers it? Without a repro case there I don't know where to start.
