Wave Curve- Seamless?

One thing about the wave curve component:

When I have frequency at a whole number and I turn up the Amplitude and/or Frequency variance, the wave curve does not start and end at the same slope or even the same height. This is expected. But I would love it if the wave curve would have a seamless checkbox (similar to the one on the noise component), or instead a reaction to the global seamless tiling checkbox.

The issue here is that if frequency is NOT a whole number, checking this seamless box would not result in periodicity. But I can imagine an algorithm that seamlessly tiles to the nearest whole number (of frequency).

This doesn't seem like it would take too much of the developers' time. How about it?
