how to introduce a new modification and specify its delta mass

[gmaddalo79]

Dear DIA-NN,

Thanks for developing such a wonderful software! Your work is highly appreciated!

I have a question:

Would it be possible to customize a modification and insert its delta mass (Like maxquant or spectronaut)? If so, would you mind guiding me please?

Thanks a lot in advance for your valuable help

Kind regards

Gianluca
