Custom InDesign Headers

Years ago, I used the Power Headers plugin for an InDesign project. I could use this type of plugin again for a catalog I am working on. When I go to in-tools.com, I see that it was last updated for InDesign 2015. Can any one recommend a similar plugin for InDesign 2024. I am particularly interested in this feature that Power Headers had:

GREP Processors: Power Headers offers the option of applying post processing to individual header variables. The processing can change the formatting and can change the content as well. This can be used to create headers with abbreviated text or even entirely different text than what appears in the document!

Thank you!
