Can we combine to different DSL rules in DSLR with a Boolean operator? Can we combine them with an OR or AND?

e.g; in DSL I have:

a or b = Person(name ==a || name ==b)

c or d= Person(name==c || name ==d)

Can I write in DRL as:

a or b or c or d?

I know combining them as one rule is easier but I have few limitations;
