Automatically create summary with only selected data

I have a blank template the user will fill out. This template can have 1 completed row or 10+ rows of data. I would like to be able to click a button that will then populate a sales invoice automatically. I would need the sales invoice to only populate with the rows selected. Either (A) I need to have the macro require the user to select the row(s) desired to add to the sales invoice and then populate or (B) have a column that allows the user to check a box or something before clicking the macro button which will then look for the check boxes and only populate that rows data.

I am more than OK with you offering a better solution to this. I really do not know how to do this....I can do this no problem with one invoice per one client (each tab is named a client) however I could have different projects throughout the year for the same client and would only want to show an invoice for project 3 for example not 1 and 2.

I will be doing v lookups to pull the other data in the row, so all I am looking for is to find/select/checkmark/etc. something in column B, and paste in column AA

Is something like this even possible??

Attached is an example file with a more detailed/updated description of what I am after. THANK YOU IN ADVANCE FOR ANY HELP!FileNeedsHelp.xlsm

It could be a lot. I thought it would be good to have a database of all invoices for history reasons. There wouldn't be any maintenance or anything to the tabs there would just kind of be there. Maybe it would be better to have a specific file that just holds invoices instead of adding to this file. Probably sounds like a better alternative now that I think about it.
