Add random interval for same link for Pinterest#2635

Hello,

I mainly use pluber to schedule Pinterest pins.

A small suggestion to make scheduling pins even easier would be to automatically add a minimum and maximum interval between two pins that point to the same link.

For example:

For my link mysite.com/interval
I am going to create 5 pins.
And I want to add a random interval of 5-15 days for the same link.
