Spike Jones 45 RPM 'box set' question

I've got a 3 x 7" box set simply titled Spike Jones Favorites.
RCA Victor WP 288
Each disk has a different Cat # listed under the WP 288 album number. 47-3287, 47-3288 & 47-3289.

I found an existing sub for what appears to be disk 1 from the set:

I plan to submit the set but, before I do I'd like to ask the best way to approach it.

A) modify the existing sub to include the remaining 2 disks.
B) make a new sub for the each of the other 2 disks and link them somehow.
C) leave existing sub alone and make a totally new submission for the complete box set.
D) something completely different.

Any input would be appreciated.

Would your box set be similar in form to this Caruso* - Caruso ?
In which case the numbers 47-3287, 47-3288 & 47-3289 can be entered in the Baoi as Matrix / Runout (Side _ label) etc.

I would choose either:
A) modify the existing sub to include the remaining 2 disks.
or
C) leave existing sub alone and make a totally new submission for the complete box set.

A more experienced than I will know which is the better choice.

Thanks for the suggestion, Laffnmules_Lode
Yes, it is quite similar to your example.

I'm thinking plan A would avoid a future merge request.
Should pester the OS before I stir up a mess?
Then use plan C as a fallback.

Wouldn't mind getting another comment or two first.
The taste of that Hendrix 10 x 7" box fiasco is still lingering.

OK I'd say 1 month is a long enough wait.
I'm going to tear into this project soon.
Last chance to speak up.

I chose option C.
