I have a few blocks I would like to use one common custom template for and I cannot figure out how to go about it.
Of course I can create N copies of my custom template each named after an individual block but then I will have to maintain these N identical copies in case of any changes - not nice. As far as I understand, the machine names of the blocks are beyond my control, at least I can't see how I possibly could [re]name N arbitrary blocks so that they follow a similar naming pattern and I could use one template for all of them.
Any ideas?
