Increase 300 character limit for Time Entry notes pulled from PSA

I would like to pull more than 300 chars, ideally 1,000, from Time Entry notes. This is because we want to pull specific time entry notes into customer facing reports being generated from BrightGauge, as this saves us a lot of time adding the text manually into reports. 

I have been told that BG is not limiting the chars and it is the PSA API, however I figured worth raising on here because the direct impact of this is data coming into BG.
