Read Strings from AB PLC Faster When Using Ethernet/IP

I am looking to improve the read speed of string tags when using the ethernet/ip package to communicate with an Allen-Bradley PLC. Currently, I am reading each string tag individually, as the ethernet/ip VI does not allow an array of strings to be read like it does with SINTs, DINTs, or any of the other data types (referring to the "Number of Elements" input of the VI). What is the proper way to read in a large amount (~100) of strings under a single tag array in the PLC? For reference, I am seeing a ~6ms read time for each read, which is acceptable until you repeat it 100 times and get a 600ms total read time.
