Using some code I've written, I've been able to successfully launch several backtests in parallel. Unfortunately, they tend to try to write to the same file in various instances, say when storing results in BacktestingResultHandler for example.

Most file output functions I have seen make use of `BacktestId` to name the file they are writing to. In my case, all threads seem to have the same `BacktestId`, hence why they're all trying to write to the same file.

Is there any way I can edit this `BacktestId` or randomly generate it? Alternatively, is there a global setting to turn off all writing to files entirely?

Thanks in advance!
