I have a shortcut to a .bat file which I pin to the task bar using a workaround by using another icon and this seems to work. Now I make a copy of that shortcut, point it to a different .bat file, rename it, and I can't pin this one to the task bar. I have to find some other new unused icon to pin, pin it, then modify it manually. The other problem this causes is that Windows seems to track which icons were pinned even if they are modified after the fact. As such, if I use media player as my dummy icon, pin it, then alter it's name and shortcut to point to a .bat file, I can't re-pin Windows media player and if I select unpin from the Windows media player, it unpins my shortcut to my .bat file.

I can't believe how ridiculous this is. Is there a way to pin anything I want to the taskbar (ie. .bat file in my case) that does not cause problems like this? 

Is there an easy way I can copy an existing shortcut and modify it and re-pin it to the taskbar? The reason I want to copy it is because I start a .bat file (in particular git bash) and I set properties on the window like quick edit, increase the screen buffer and set it's position and size manually. I don't want to have to do this to every single icon I want to pin since they will be identical aside from the shortcut url.
