vtour stereo ?

I can make single stereo panorama with vtour(multires) or vtour(vr-opt) droplet. Working fine !
I try to make a tour with 2 or 3 stereo views named (1view_l/1view_r, 2view_l/2view_r,...) but the result is a tour with multiple mono panos (1view_l, 1view_r, 2view_l, 2view_r, etc...)
So, is it possible to make a vtour stereo ?

I find the mistake...when the names are 1view, 2view, 3view, etc it doesn't work with stereo. If the names are view1, view2, view3, etc. it works.
