MEP class rating included in CPL training?

[MyIDisthis]

1) Can the MEP class rating be included as either a part of the 15hrs in the ME-IR, or a part of the CPL?

2) If I take the whole CPL course on a single engine aircraft ( whether it's 15 or 25 hours ), then the 6 hrs of MEP class rating and combine it into one skill test - that will give me a CPL with MEP class rating.

Until not too long ago I thought that just like with IR there was a CPL-SE and CPL-ME, but of course there's no such thing. However, could someone just confirm that combining the skill test as written above will give me the right to work as an airline pilot. Because you only need two skill tests, one ME-IR and one CPL/MEP class rating, right?

Thanks.
