Import data from web to excel and add aditional column with manual data

Hi all,

I Just found out how to import data from a website. Fantastic tool!

However, I have some difficulties:

1. I would like to add an aditional column, with my comments that I put manually.
The problem I get when the info is updated, is that more rows are included in the excel so, the info in my new column does not match with the right row any more
Any magic solution to this?

2. I get the web-data from a site, in which I need to introduce my credentials.
The data in the excel is not updated automatically, because the session is expired. It means that I have to introduce each time my password to the site in order to get an updated version.
Any idea to fix it?

Thank you SO much in advance!
