Can multiple Form 4868 be placed in same envelope?

When filing automatic extension of time to file with no tax due, can multiple extensions with the same address be placed in the same envelope or need they be mailed individually?

Did some research and it appears they can be mailed together. Here are the instructions for how the IRS processes when multiple forms are in the same envelope.

Occasionally multiple forms 1040/A/EZ/X are attached. For example:

Two or more returns from the same taxpayer are mailed in the same envelope

Two or more family members' returns are mailed by the tax preparer in the same envelope

Two or more unrelated returns are mailed by the tax preparer in the same envelope

Note:

Detach the returns leaving an action trail on each document, then sort, work or route the returns as appropriate.

However, the IRS is tracking an issue in their issue system about multiple filings in the same envelope and several getting marked as late.

IMRS 10-0001371 – Multiple Forms 7004 (Request for Extension) mailed in one envelope Issue: A tax professional mailed multiple Forms 7004 (Request for Extension) in one envelope to Ogden, postmarked 3/15/10. Six of these were rejected, with the taxpayer receiving Form 6513 stating the extension was not approved because it was filed after the date the return was due.

So because the IRS has had a recent problem with multiple filings in the same envelope, I would go ahead and use more than one envelope.
