The website Lot Calculator does support that, but you need a barcode scanner to do it.  You can search via UPC so you can scan items with the scanner and have it automatically fill in that search form on the tool.   It will find the item and quickly add it to the list.

I will make a note about supporting this in the app though.

Is this feedback for the website lot calculator or the app lot calculator?

Added all of these sets to the site a while back.  The base set is here:

I am not seeing an English version of this card.  We do not track Chinese language Riftbound cards at this time.  If there is an English version, please post a photo of it.

Added that Alt Art card now.

Sorry for any problem. I've asked servers to revalue and recount everything. That should be done by the time you get this, but sometimes takes longer on really big collections. Sorry for any inconvenience.

Thanks for reaching out. I've added that set to our list of sets to add. We will add that full list in the next few days.
