edit queries online

hello guys. 

i created a PBIX file from powerbi desktop and the file size is 731MB.

and data sets are multiple excel files from my desktop. i published it and it took me 3hours or more to complete. which is too long. maybe because of my internet connection. 

my data sets are below

7 excel files - referrences tables(small files) 1Mb Max

1 excel file - 2years historical data (large file) 700MB

1 excel file - which i need to update everyday(around 40MB Max)

ok so here's the problem

i want to edit queries from online, i want my pbix to get data from my one drive. but i really cant find how to edit my data sources.

please help 

thanks in advance
