Warping window in "findsignal()" for dtw as TimeAlignment.

Hi! Is there any way to to implement a warping window in the function findsignal() when using 'dtw' (Dynamic Time Warping) as input for 'TimeAlignment'? Preferably a Sakoe-Chiba band. I know some warping path restrictions are available in the dtw() function, but I could not find anything in findsignal(). Just wondering if I've missed out on the obvious solution.

At the moment there are no warping constraints used in the FINDSIGNAL variant of DTW.

I'm usually successful at coaxing it to work by using normalization constraints, but your mileage may vary. If you post your signal(s) I can try to take a stab at it.
