[wix-users] How To add an feature after installation

[RonnyS]

I install a program within a large installation of other programs.
A certain feature of my installation is intended to be not immediately
installed.

Later in the large installation, should the feature be installed.
How can I install a feature later?

Am I on the right track, to control it via the feature conditions?
Or do I have to use an extra MSI in burn?

Thanks Ronny
