Creating external table - from a file with multiple field separators

Question

I need to create an external table from a flat file containing multiple field separators (",", ";" and "|").
Is there any way to specifiy this in the CREATE TABLE (external) statement?
FIELDS TERMINATED BY "," -- Somehow list more than just comma here?
We receive the file from a vendor every week. I am trying to set up a process for some non-technical users, and I want to keep this process transparent to them and not require them to load the data into Oracle.
I'd appreciate your help!
