I'm using the software Duet's "mouse & keyboard control" feature to control my Mid-215 MacBook Pro and my 2021 Macbook Pro, both from the keyboard and trackpad on my 2015 Macbook Pro. Almost everything works perfect, including key commands but I noticed certain click related modifiers do not work.

Such as clicking a file, holding shift and clicking another file...does not work to select that range.

Also holding option and clicking and dragging does not make a copy of the file.

Is there a way in BTT I can map these modifiers? I'm optimistic it can work while using Duet, because I already use BTT to set the shift key modifier to block vertical scrolling and the option key modifier to block vertical scrolling.
