Not currently no, but you could run a loop via an at begin of scene
action, which uses the jump to x action part to create the loop & then before it you would add various change lightmap action parts & pause action parts to control when it should change the lightmap.at beginning of scene
action parts below.
pause for x seconds/milliseconds
Set lightmap of scene 'current scene' to 'new lightmap file'
jump to action part 1
You would of course need to quit this action inside of an at end of scene
action to kill the loop when it is no longer required.
P.S: this was just a quick mockup of action parts. You could control it better by combining a value & if queries to determine which lightmap would be shown next, which means it would always change to the correct one no matter which lightmap is currently active when you change to the scene.
