I've been trying to figure out if it's possible to restrict the innerblocks available in some of the core block. Right now I'm looking to restrict what can be used inside core/media-text and core/column. I have yet found a way to do this.
Before I plan on building out custom version of my own I thought I would ask and see if anyone knows of a way to do this that I haven't come across yet. I'd prefer to use the core block if possible.
