Hi Beka,  
In the current version there is not such a function.  
We will include this function in the next release of Collect (3.21.0) by the end of next week.  
You can try to create a workaround: use the sum and count functions. E.g. sum(entity\_name/attribute\_name) div count(entity\_name).  
Thanks,
