DS2072 - 56 Megs, RS232 decode, max Event Table entries = 169?

[Circlotron]

Decoding a number of RS232 data bursts and trying to compare them. Each one is 67 bytes, 69.65mS long, every 340ms. In each burst only bytes 2 & 3 are different. Trying to record as many as possible and paste them into parallel columns in a spreadsheet and see what is going on.

Open up the event table and there is only 169 entries maximum.
Is there any way to make this larger or is that the set limit?
Memory depth = 56 Megs.
