Moving a Window With a Name Containing (...) to the Current Workspace

[JMichaelTX]

But it appears that in order to select a window, it must already be in the current workspace; otherwise I get an "Action Failed; ... could not find any matching windows ..." error.
Is there an alternative way to get a hold of a window?

Take a look at this macro set by @_jims:
Desktop Spaces • Macros for Navigation and Window Management

It looks like (although I have not tested it) that he may have solved issues like this.
