Heltec HT-HD01 v2 Transmit Power

I have two HT-HD01 nodes that I've flashed with the latest firmware. When I try to configure output power, I'm limited to 21 dBm. I think this is the limit for the v1 hardware. The v2 hardware should have an upper limit of 27 dBm (according to the website). Is this an issue that can be addressed? Increasing transmit power by 6 dB should double my range (assuming good line of sight). Should I write an issue on the AREDN GitHub or there an upstream project that I should write it against? Thanks.
