EcoOnline public idea portal

If I want to search for a new chemical, maybe a replacement 7 substitution for a chemical, I would like to add requirements in the search like must include any substances listed in the candidate list. Today I have to search for possible Products in the global search, download interesting Chemicals to a local Place and then I can run legislation checks and find out if the Product complies with my requirements or not. I would like to do that search without having to download the Product.
