Is it possible to use indirect tags in an expression? Basically I have a window with multiple numerical displays that currently sum several unique tags of a particular machine. Curious if I can convert this to creating the tags indirectly or is it best to just build the tags in the Client Tags and then point to them indirectly?

Yes, you use the tag function. The tag function returns the tag’s value and the argument is the tag path. You can do something like:`tag("[default]Folder1/"+{Root Container.var1})`
