Hi, in order to solve the clear lack of attention brought to the currency issue in Hubspot
(see here, here and here), a solution could be to improve the conditions for Calculated Properties.
As such, I would expect to be able to use as a condition: If "Currency" is not 'EUR', then convert "Monthly Recurring Revenue" to [insert currency formatted property]
This would only fix one of the lacking features around currency, but conversion is a big one.
