Connecting identical field entries

Apologies if this has been dealt with elsewhere. I’ve searched but not found anything. Probably not using the correct terminology.

I have a piece of data - a field entry value - that is common to several vault entries. When I change it, I have to remember every vault entry that uses it and change these all to match (without human errors). Is there any means of designating one vault field as the ‘master’ and then tell all the others to reference that field and whatever happens to be the current value in it? That way I only make changes to one point in the vault and the effects of that change are propagated throughout the other entries automatically.

Thanks in advance.
