Multiple SQ versions share user or data folder - Customizable file path

      To add, recently I mainly developed strategies on 137Dev4, optimized strategies had to work on 136, and occasionally needed to check if there were the same bugs in the latest 137rc3. so when every commodity rollover, I needed to download and update the commodity history data repeatedly and often. For Asian market data, I even need to manually import historical data one by one repeatedly, which is quite tedious. If it is difficult to customize the whole user folder, at least it should be possible to customize the data folder. Just like the strategy output save path can be customized, no matter I use several sq instances or two PCs to develop and retest the strategy, it can be easily shared and managed under one file path.
