What problem is your feature request going to solve? Please describe.

Description: Background: The Loop Grid widget has the option to create Alternate Templates. These Alternate Templates have the option to repeat itself every nth item: https://capture.dropbox.com/U2dUyauUY02Qg7pb
For example, if "Position in grid" is set to 3, then the Alternate Template will appear every 3rd, 6th, 9th, 12th, etc item. If it is set to 7, it will appear every 7th, 14th, 21st, etc item.

Describe the solution you'd like

Feature Request: Allow offset repeat; i.e. "Position in grid" defines initial offset position, and new setting called "Step size" (or similar) defines repeat step size.
For example, if "Position in grid" is set to 3 and "Step size" is set to 4, then the Alternate Template will appear on the 4th, 7th, 10th, 13th, etc item.

Similar to CSS nth-child functional notation: https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-child#functional_notation
