Merge Sunday Daily bar with Monday in MT4 ?

Is this now possible & if so, how, please ?

I'm using FXCM's MT4 which generates a Sunday bar : I want only 5 daily bars / week.

A standard feature of some other platforms allows one to create a custom start time for the first bar of the week to run from Sunday Open to normal Monday Close, so I'm looking for code that will do this in MT4.

And the answer is.... go back to using NinjaTrader charts, just use the free demo version with free EOD FX data...

Ho, hum... simple really....

Edit : now up & running and SO good to be with the superior platform I used for almost 20 years as a daytrader (now retired).
