Timequest: toggle synchronizer constraints?

I've figured out one method that defines the signals on each synchronizer clock input as a clock that is then placed in its own asynchronous clock group;

#  sync_pulse.sdc
#  Find all the synchronizers in the design
set regs 
#  For each synchronizer find the name of the signal driving#  the clock input port, and create a named clock constraint.#  Name the synchronizer inputs sync_pulse_input${n}, where#  n = 0, 1, 2, etc, so the synchronizer input names can be filtered#  from # 
set n 0
foreach_in_collection reg $regs {
    set clk ]
    create_clock -period 1000 -name sync_pulse_input${n} 
    set_clock_groups -exclusive -group 
            
    incr n
}

TimeQuest now identifies the signals as clocks, and I named them such that if I wanted to do something with the real clocks in the design, I could easily distinguish between the real clocks and sync_pulse inputs. Eg., this design has two real clocks, the JTAG and 50MHz input clocks, and three synchronizers

tcl> set clks 
_col17
tcl> query_collection -report -all $clks
altera_reserved_tck
clkin_50MHz
sync_pulse_input0
sync_pulse_input1
sync_pulse_input2

This achieves the goal of informing TimeQuest that each synchronizer input is a clock-like signal that can be ignored.

Am I abusing TimeQuest using this particular method?
