Multiple Alternate Surfaces

Question

Hi folks, is there any way to assign a point in a template to more than one alternate surface?

I would say 'No' if you are strictly refereeing to the Alternate Surface option within a template. If you assign an alternate surface to a point that is also part of the Top Terrain, then it can be in two different surfaces terrain models. 
 There is also an ability to create terrain models from elements. This can be used to assign features from a corridor to multiple terrain models. These terrain models from elements will follow along as the corridor template is modified. So, in that way it seems to have the ability for any one point or feature in a corridor to be part of as many Terrain Models as you may need. Not sure if that helps but it may be useful in some instances.
