Hey Johnattan,
Typically, countries follow the official list - which will never be perfect. In some countries this is particularly sensitive, because it represents a specific period in the history.
There are a few approaches you could take, but none are real solutions. I would myself totally not be in favor of just 'adding monuments to the list'. Only in the case of a technical/clerical error, I would suggest to do that. But this sounds more like you disagree with the government on what the definition should be.
What they did in South Africa, if I recall correctly, was to create a separate list, where people could make suggestions for buildings to be recognised as monument - a list they would pass on to the government at the end of the competition. You could even ask people to submit photos for that, but those would - I think - be out of competition.
Best,
Lodewijk
