Slideshow and time between photos

Hi,
When I'm in slideshow mode I'd like the time between photos to be reset after a rotation
I changed the L key like this, but it doesn't work because it's like I'm in viewer mode and the time is not reset

@if:Show VIEWERCMD=slideshow
Image ROTATE=270 HERE REPLACE
Show USEEXISTING VIEWERCMD=rotate,-90
Show SLIDESHOW LISTSIBLINGS FULLSCREEN
@if:else
Image ROTATE=270 HERE REPLACE
Show USEEXISTING VIEWERCMD=rotate,-90

I also tried
@if:Show VIEWERCMD=slideshow,on

The viewer has its own commands (e.g. for toggling slideshow mode in an existing viewer), which are different to the ones you'd run from a lister (e.g. to open a new viewer in slideshow mode).

You can find what most of them are by looking at the viewer's toolbar and menus.
