How to open included file(s) from within the worksheet

When a Mathcad Prime 2.0 worksheet has another Mathcad (Prime 2.0) worksheet(s) included (using Include Worksheet button) , there is no option (say, by right clicking "Include<<" right on left side of the included file) to back open this file later from withing the parent Mathcad worksheet. It is easier than using the Windows Explorer for the user to take a view at the included file or to edit as required.

I find similar use in some other 3D-design softwares - not only very helpful but also not able to do otherwise.

Pl. comment

Best Regards.
