How to animate octane's different values, in Poser?

Hi,

Is there a way to animate Mix node’s value from poser?
I need to animate mix amount on two different displacement
maps, so that one slowly changes into the other one as the
animation progresses…

Any Suggestion Would be appreciate.

I didn’t find right solution on the internet.
