If your sheets data are (or can be) formatted as Tables you can easily to this with Get & Transform aka Power Query with no advanced understanding of Power Query:
#1 Setup a query (as connection only) that combines all (or selected) Tables in your workbook
#2 Create another query that references (refers to) the above one. Filter the table on the column that indicates if a project is quoted or not
==> The filtered query will load to a new sheet as a Table
#3 Edit the connection only query (above step1) to filter out the Table created by above step2
Then on your demand (or auto. every n minutes and/or when the workbook opens) refresh the resulting query to get up to date info. from the sheets' Table
and that's it
That's efficient and having data structured as Tables allows making almost any analysis you can think of...
If interested I can provide a sample as long as you can post a picture showing one of your Tables (or better share - via OneDrive, Google Drive.... - a representative sample workbook ) + I'll need to know the column name to filter and to filter on what (y/n, yes/no, 1/0...)
