Folder for text / SMS messages?

Hi! New-ish user here. It looks like folders can be created for “Messages” but not “Texts’ in the app. This would be helpful to organize SMS texts...for example, when a text message has been actioned so you want to move it out of the main display, but need to reference it later. 

The app we used previously, Texting Ninja, had an “Archive” function that did this (not to be confused with RC’s Archive function). 

Is there any way to accomplish this type of folder organization for texts? Is it a roadmap item? Thanks!
