Expression maps and media bay?

I am working up some custom expression maps for East West’s orchestra.

I have these saved in a specfic file location.

When I drill down in Media Bay to this location I find nothing showing.

I have the results filer set to show ‘All Media Types’.

I see that HSO can be found but I think they are track presets

Are expression maps ‘track presets’ ?

Is it possible to find them in Media Bay

Would be handy to save a EW Expression Maps folder as a location and have it show in Media Bay.

Any solutions please?
