Is re2j able to combine multiple regex into one?

Basically, if there is a large number of regular expression, it can be quite slow to match target strings. So I am looking for solutions to "compile" many regular expressions into "one".

https://github.com/fulmicoton/multiregexp provides a solution to build a large DFA based on each DFA built from each regex. However, it has many limitations - only a subset of regex is supported.

Is there a way to achieve what I want using re2j? I tried hard but could not find related info.

Thanks in advance.
