I've never seen such an option before, I wish there was one.
The scale is calculated by the program somehow and it re-calculates it (usually wrong) every time a new model is added and views are created with the new model.
It's particularly annoying when a change of scale is desired. You have to make the change to the currently active model, then activate every model used for views on the sheet and change their scale, too.
I've use Drawing relations in the past to try to link all the scales. Equations with something like "scale:13 = scale:5" but it's not convenient. I wish there were a parameter that would make the default the last scale used, but as far as I know, there isn't.
