Apart from the neobroker support, are there special places where you can make suggestions for share savings plans?

Most of the time, all I get back from support is some kind of garbage. What annoys me the most, for example, is $HIMS (+3,2 %) and $EXR (-1,24 %) which are available in the savings plan at TR but not at SC. I bought them at SC a long time ago when they were not yet available as a savings plan at either NEobroker. Now they are available at TR but not at SC in the savings plan xD
