Of course...

if your props have allready an animation, then you use something like this:

action MyProps()
{
while(PropHealth > 0)
{
...do something
wait(1)
}
ent_animate(see manual);
ent_remove(me);
}

You can use health for it, or simple a number like 1 for ok and 0 for destroyed. In this case you can use while(Destroyed ==1) or something.

Hope that helps you.
