Hi there, @Abdul Rehman.
Thanks for sharing your thoughts here in the Community. At the moment, the option to select a default company as you sign in to your QuickBooks Online (QBO) is unavailable.
While we're still improving our program, I'll make a note of this concept for consideration in our future product enhancements.
Meanwhile, I'd suggest you visit the QuickBooks blog regularly to keep you updated about what's new in QBO.
Feel free to visit us again at any time. We're always here to answer all your concerns. Have a nice day.
