Description
Describe the solution you would like.
As discussed during ongoing ICES course on SS3, expanding the M option 3 to allow a matrix of M by age and year would make life easier for those with SCAA-style models that include a matrix of M.
Describe alternatives you have considered
Status-quo option requires annual blocks on M-at-age parameters.
As noted by Max (@akatan999), for EWAA models, it might be nice to input an M matrix in the wtatage.ss file. However, this would prevent it's use in a model with parametric growth and maybe require more complex coding to implement.
Statistical validity, if applicable
