Joining more than two streams of data in logpoint query language

Hi Team, currently, my customer could only join two streams of data at maximum using join queries from pattern-finding expressions. Are there any recommended queries we can use two join more than two streams of data?

I understand that creating tables and using process lookup commands is one way of doing this , but creating multiple tables and populating them one by one and then using it in the query is a hassle I would not want my customer to go through. So is there some native support in the query itself for performing these multiple joins at once?
