Link photos from internal storage to Lightroom Mobile for IPad

Hi guys,

So I'm on a trip through south east asia and wonder about, how I can change/ stop the storage location for lightroom mobile on my IPad?

I would like to do the same workflow like on Mac/Win. Copy my photos on the internal storage of my IPad via Data-Manager, then link them to lightroom mobile to select and edit. Then move the photos from IPad to an external SSD and relink them, to work with them from the ssd, if needed.

So if I copy the photos to the internal storage and add them to lightroom mobile, lightroom not just import/ link them, it's starts to copy the photos to the app and I loose the double of the internal storage.

I could also add the photos directly from the SD Card to the lightroom album, without copy them via data-manager, but how do I move them after I finished editing?
