Service catalog resource questions

I have 2 questions regarding Service Catalog resource questions :

1) Is there any way to delete questions from the pool of existing questions?
      There are some old questions which were created during a workflow testing period,        and they're no longer needed

2) Is there any way of adding a question as a multi line plain text area (HTML text area form element) instead of a single line "plain text" input (HTML input form element)?
