Is it possible to pass multiple values to Oracle ERP Cloud from ARCS Data Management?

We have a Oracle Cloud ERP custom BI report with parameters that accept more than one value.

When creating a connection to this custom report, I used the following parameter line:

$BU$,$START_PERIODKEY[MM-dd-yyyy]$,1217,5921

and it works as expected. However, passing multiple values for the third and fourth parameters makes the report fail:

I tried the following:
$BU$,$START_PERIODKEY[MM-dd-yyyy]$,"1217,3204","5921,5922,0000"
$BU$,$START_PERIODKEY[MM-dd-yyyy]$,[1217,3204],[5921,5922,0000]
$BU$,$START_PERIODKEY[MM-dd-yyyy]$,"[1217,3204]","[5921,5922,0000]"

None of them work. so is it even possible?

I think this is a legitimate support question. I did open a ticket but they think Customer Connect is better than them to answer this question.
