Trend lines replication or preservation on various asset / TF

Hello fellows,

i am searching a way to :

> replicate automatically all the horizontal and trend lines that i manually add to a graph of a specific asset to the other graphs of the same asset

> keep all the horizontal and trend lines that i manually add to a graph when i change timeframe (as MT4 seems to cancel all the lines when you change TF)

Thanks,

LS
