Hello There ! How to change a picture that placed near a symbol name when we using cBot ?

Hello There!  Could someone give a suggestion on how to change an icon that placed near a symbol name when we are using Cbot? 

as we all know that on ctrader platform we could set an icon that placed near a symbol name on each chart from  A, B,C, D to H. 

to make it easier for traders to distinguish the differences on each chart.

but when I'm using cBot on a chart it will automatically change back to the trendline icon instead of an alphabet icon that I have set earlier.

so Is there a way to change or fix it? 

Thank you.
