Is there a way to control the "optimize" function of IDM?

We have a situation where a change to the case of attribute did not make
it through from one eDir tree to the other because the modify was
"Optimized" on the Pub Channel of the remote tree.

I've already spoken with the programers about this and advised them to
remove the attr and re-add if just making a change to case, but I want
to know if, as the IDM admin I have any control over the behavior of the
Optimize.

Thanks !
