Question about adding multiple child records using Focus Task table

In using the method described here:  http://www.quickbase.com/quickbase-blog/how-to-quickly-create-multiple-child-records-in-quickbase 

The instructions state that the Focus Task table is created and uses a look up field for the Related Project, figure 5 in the instructions.  The instructions then go on to ask that you create one and only one record in the Focus Task table and that record has a Related Projects field of 1 which was manually entered.  Is the expectation that in order to use the functionality, a user would need to manually update the one record in the Focus Task table with the project id of the project where the button lives?  Is there an automated way to tie the created task to the current project using this method?

Thanks!
