Shoppify Mappings COO / Last Cost / Pricing

Hello @simonliang91 @KarthikGajendran et al. 

I was looking through the mappings and wanted to see if we have any updates to the following:

& 

For Shopify integrations I have the need to map:

1. Country Of Origin - I don’t see this as a field value that is mappable in the entity screen and it is not mapped out of the box. 
2. Last Cost vs. Current Cost - i know there are couple threads out there (one that I started) but it seems the customization focuses on Matrix Items.  It would be nice if we had the option to choose which one, as I have an example where the valuation is FIFO and it is not pulling last cost.  It is pulling the current cost (from Standard Cost) so this is effectively 0 in our scenario. 
3. Pricing - a general question - does the mapping consider sales pricing at all?  either promotional or worksheet based (non b2b)?

Cheers,
