Filtering objects using show-objects by several types simultaneously

[smalash]

Hello. I have two questions

1. Is it possible to run show-objects query that filters on multiple object types?
According to the documentation, you can only specify one type
https://sc1.checkpoint.com/documents/latest/APIs/?#web/show-objects~v1.8%20

2. Where can I find a complete list of types that can be used in the "type" field for any version of the product (especially interested in R81.10)?
A list in the format as in this article is enough for me - https://community.checkpoint.com/t5/Management/R80-Management-API-tips-and-tricks-quot-show-objects-...
