Stroke reveal? Similar effect in Synfig?


I have a few lines I want to mask reveal so my question:

I was wondering if there is a ‘stroke reveal’ type effect. Say if i draw a line with the Spline Tool and then set a parameter for the stroke to move along that spline? Sort of like 0 - 100% ?


Have you seen this?
It is a little outdated (version 0.63.00) but it should still working with any later version.
