Demisto-sdk upload doesn't allow override

[warm20]

Hi Community!

I have a question since i can't find answer anywhere.

I wonder how the demisto-sdk community update the content pack when there is a code change, in my experience. i need to upload the same pack sometimes because I changed one script but the command doesn't allow me and there is not force option.

the error message is like :
Could not create integration with ID 'xxxx' and name 'xxxx'. Custom item of type integration with ID 'xxxx' and name 'xxxx' already exists (xxxx) (100017)

i wonder how to get around this and if this is not best practice, i'd like to get some guidance. 

thanks you all!
