Ive searched around and havent been able to find anything regarding using a specific "template" as a target to trigger when to show custom meta boxes...Is this possible, and if so how would you script this out?
If post/page ID's are the only real feasible option then would it be possible to target a parent page ID rather than individual page IDs?
EDIT #1
To help further explain the particulars of project Im going to briefly outline why Id like to instantiate custom meta boxes for only particular page templates...
The way my site is currently setup is have a bunch of custom static pages for artists on a record label. Originally this was perfectly fine since they did not need and/or request a more dynamic solution - however now they are currently needing to frequently update their own bio/pics/etc for each artist profile page making my current setup not very useful.
Currently, there is a Recording Artists page that acts as an archive, and then all artist pages are children of that page.
Additionally, I also need to allow personalized widgets to each artists sidebar which is a key part of deciding which direction to go.
The only other alternative Ive considered but Im not sure if it would work is to convert the recording artist archive into a CPT archive instead, and then make each artist page a custom single page...
