Not as far as I know.
Only suggestion I can make is to see if there's a way to do this either all in the same window or by hiding the other window until they click the button so that you don't see the window flash.
Thank you PhilModJunk for the answer! The whole point of it is that the user can see both window at the same time and clicking on several buttons sequentially while rearrange and adding jobs to the planning so hiding the window is not an option here, but worth to remember.
In the same window, maybe haven´t consider it when it will cause the layout to extend outside the screen of a laptop. However for the users doing the most planning I have suggested a bigger screen in order to get an overview of all data needed to consider when doing the complex planning of teams of personnel, equipment and location. The purchase is under way so maybe it would be the best solution even for other reasons.
I have read several good answers on post here at the forum helping me and nearly all of them posted by you - so thanks again for beeing so extremly helpful and busy :)
