Is there a way to tell TimeQuest that all signals launched by State A and captured by State B are part of a multi-cycle path? My combinational path delay is too large so i'm adding a timer to delay m...

A multicycle applies when a register is clocked not at every edge but every other edge or so. In your case I assume by timer you mean clock_enable. If so you can apply multicycle to all registers activated by clock_enable.

Edit: Similarly a multicycle applies if data is known to change every other clock or so. However just having data delay is not a case for multicycle approach.
