Feature request: Separate meta columns for each fixed currency price

I have to bulk edit hundreds (maybe thousands) of variations to that the regular prices are fixed for 3 different currencies (default 2 others). As it stands, the values from a single product that I edit with Multi Currency plugin installed for the 2 extra currencies, creates one extra Meta field with both currencies prices. The meta column is called: _regular_price_wmcp
and the content example looks like:
{“GBP”:”49″,”USD”:”59″}
This makes for extremely difficult bulk editing because of the way it’s formatted – completely different to standard regular price columns.

I use PW Bulk Editor – which doesn’t “see” the column at all, and using Woo’s own exporter gives me a horrible column to try to edit in Excel.

Surely it doesn’t have to be so complex??
