Make us able to turn villager workstations off for decorating

I let my villagers free-roam in their little town and I love decorating it. Sadly every time I place some barrels half my town becomes fishermen. 

I would love a button in the UI of the workstation blocks that disables villagers from using it as a workstation. 

A hidden button in the UI would probably confuse some players who don't know about the feature, and a visible button with text adds clutter. I think making the button appear as a toggleable command is the best solution! With it being off by default. Something like /gamerule enable_workstation_bypass

If that's too hard I wouldn't mind a small button, with text explaining the feature if a player hovers their cursor over it.
