Modify "Show Trade History" operation in MQL5/MT5

I trade multiple time frames of the same symbol, using the same account, with a custom Expert.

I also like to keep the "Show Trade History" option on when trading, as I find the graphical information of value. 

However, as I trade multiple timeframes, the charts become overly busy with trading graphics, particularly at the higher time frames, as these show all of the lower time frames as well..

Each time frame runs with a different version of the EA and has a different magic number. Also, each position that is opened includes the timeframe information within the Comment field. Hence it is possible to identify the originating time frame for every singe position that has been opened, either through the Comment field and through the magic number.

I would like a solution to limit the functionality of the "Show Trade History" such that for each time frame chart, only the positions opened on that chart are visible. Alternatively, the "Show Trade History" functionality can be disabled and a new graphical function/class ect. can be provided that will mimic the same functionality, but limit it to the time frame of the chart where the position was opened.
