Size of zbrushes

Please, I need a piece of information about the following:

Using ZBrush 4R6P2

Let’s suppose I’m using a Zbrush, with a certain size;
when I re-open another Zbrush (already used with its own size), this second one will open with the same size of the first one, so not keeping the original size.

There is some way for assigning a size to a Zbrush, and maintaining it during the whole session?

Thank you!
