Add new dimension or expression in Fast Type Change

[#1]

I have created a trellis bar chart that includes supplier, data types and number of files received. I would like to do a fast type chart change to a straight table. Is there a way to display a new dimension and/or expression in the straight table but disable them when you view the data in the trellis chart ? I don't see a conditional logic that can be used to disable or make a dimension or expression invisible in between fast type changes.

Any idea is appreciated. Thanks.

Perhaps there is a way to enable a column you disabled using some kind of marco.

I mean this: you can disable dimensions to not show in a chart/table. What if there is a way to enable such a dimension again on switching using a Fast Change?

Would be really nice to know how to do this
