Adding the ability to choose what number type is exported

I would love for there to be a way to choose what number type you can export when exporting lead and application lists. Right now you are only able to choose the primary number and not mobile numbers. For being able to communicate by text it would be helpful to make sure I have their mobile numbers and the only way for that to happen is if the mobile number is their primary number. This would take a lot to change that for all of our leads right now.
