Add no crop or make square option for especially Instagram

I've been looking for adding square border with no crop options on lightroom everywhere and it's a shame that although Instagram has been trendy nowadays but this option is not available on android version lightroom or Photoshop express. There're lots of people out there capturing different ratio and both horizontal and vertical photos, edited in lightroom but have to export to another app to add a square border without cropping the image. Hope this feature will be includes in the new update
