How to reupdate photos after updating a custom brush

[MidnightRacer]

I have a custom brush for tinting/adjusting eyes.  I have edited many photos with that custom brush.  Then I tweaked the brush and updated it with the same name.  Now I want to apply the new settings from that brush to all my photos that are using that brush.  How do I do that?

My understanding is this-

When you apply a Brush adjustment, the brush settings are written in to the catalog.

To change the settings of the brush adjustment you would need to click the pin of the brush stroke (make active) and it would 'update' to the new settings you have defined for that brush.

I have no idea how you might affect a change to "all..photos" for one particular 'brush', if there were even possible.

I await other ideas out of interest.

Yes, I know that is how to do it for one individual photo.  But I have hundreds where I want to "update/reprocess" the phot using the new updated brush settings.  So I am looking for how to do that in batch.
