Focus Stacking Integration LR + PS

Hello, 

I am focus stacking by editing RAW files in LR + edit as layers in Photoshop + Auto Allign and Auto Blend. However, when I save (not save as) I do not see a new file and neither do I find a new file back in Lightroom. Can anyone help? All tutorials I've seen online deal with Lightroom Classic and check stack with original to ensure the new file is easy to find back in Lightroom next to the original files, but this option isn't available on LR as there is no external editing preferences. The only solution for me at the moment is to export in Photoshop, but I'd like a more seamless solution. 

Thanks in advance!
