You can tie-in multiple low point drains on dry systems together. it's actually a "shall" for multiple branchlines. NFPA 13 2013 & 2016 8.16.2.5.3.6 Tie-in drains shall be provided for multiple adjacent trapped branch pipes and shall be only 1 in. (25 mm).Tie-in drain lines shall be pitched a minimum of 1⁄2 in. per 10 ft(4 mm/m). This section was moved to 16.10.5.3.6 in 2019.
I don't see any reason you couldn't provide tie-in drains post drum drip either.
