How can I efficiently update common text across all products?

Sometimes we have to change an address or a number in a what I usual call a “generic text”.

It would be really helpful if we add a “generic texts” tab like the one we have in “brand”.

That way, we would only have to make changes to those texts once, in the same tab.

Ex.: it would be very useful if I have similar texts in all products… that way, if I needed to change something in all products I only need to change it 1 time.
