Enhancement: Show an error if filename based settings are repeated (like specifying flags twice)

Is your feature request related to a problem? Please describe

Not exactly a problem, but might be helpful to a lot of people, but would definitely make a difference for the Metroid dread community.
{b} is awesome, but 1 part of it does not fit what we need it to do.

Describe the solution you'd like

when using {b} or possibly another {unpicked letter} can be used to have the exact same thing, BUT instead of skipping, it can "start" the timer once again when the timer is paused. Just like when using {p} for image 1 and using {p} again on the 2nd image to start the timer to run again.

Describe alternatives you've considered

Tried using {b}{p} in hopes it would start the timer again, but understanding that {b} skips when the threshold is under it does not trigger the {p} to start the timer again.

As mentioned on Discord: https://discord.com/channels/567370425903087637/567372353403617290/1341976404325175450
You probably want to use {pb} and not {p}{b}.

I should add a warning when parsing files if a setting is repeated.

This can be closed, thank you.

I'll leave this open because I want to add more checks and a clear error message here.
