Ukrainian Grivna is set as the PBA-S currency in Regional settings. Webmoney plug-in is configured. Is it possible to use the plug-in for both currencies WMU and WMZ?
Please clarify if WebMoney implementation in PBA-S allows usage of currency other than the system one.
PBA-S plug-in doesn't take currencies into account, it simply sends requests similar to one below:

WebMoney should be able to convert currencies between purses of provider and customer.
