Discovery DataSource JNDI name Dinamically

Hi,

I have one application with 3 databases and I want to know if is there a way to
pass dinamically the datasource JNDI name configuration to my DataService
project as a parameter or discovery it internally at my Dataservice Projetc.

The scenario is the following:

I have custormers wiht 3 dinticts profiles, if the profile's custormer is 1, I
wanto to record the customer at the database_1 with JNDI data_source_1 and to
the customer profile 2  database_2 with JNDI data_source_2 and so on
