GA4 and conversions - Same field's name for "Number of conversions for an event"

Hi,

 
the metrics "number of conversions for and event" and "user conversion rate for a conversion" are note unique, they have the same name if you have more than one conversion. So, it creates some problems on some pivot tables, tables, or when you want to create a new field based on these values because data studio aggregates all values from these different metrics. 
 
I've tried some alternatives with filters for instance, but doesn't work or data is not consistent. It's a big problem on Looker, because it makes very difficult to extract conversions from a specific event.
 
Is it planned to resolve this ? 
When you create a field , Is there a way to say to data studio i want this specific metric (with an ID or else) ? becasue data studio aggregates fields with same name
 
Best !
