What method alter dims style across all templates in one save?

Hi,
V7
I am altering annotations dims style , for example 0.2inch tall, in one template but wish to then see that style update across all my default and user made templates.

In fact I would like to make the Rhino properties be saved to all templates as its going to take ages doing each template one by one to match V5, have already done it once but with Model Space Scale 10, now having to redo the whole lot again to MSS 1 and assoc entries. (Grrrrr…we should have been warned).

How is this done in as few steps as possible ?

‘save to all’ as such !

At the moment I open another template and the old style is still there, so I go through it box by box.
