Webhook custom template variable size limit of 255 bytes

Any plans to increase the 255 byte limit on the data argument of the Particle.publish() method? I’m reaching the limit primarily due to the length of the access token (~230 bytes) I need in order to authenticate with the end server, and also because I want to limit the use of the WiFi to conserve battery so I’m sending all data (~40 bytes) in one request.

I’m referring in particular to the custom template variables data argument.

Thank you,
