Transaction: attached,pending and conditional

Hello all !
There are a couple of questions on the Symbol platform:
Question 1: I looked through the information about Symbol, but I didn’t find the answer to the question - is it possible to save and transmit the “attached” information with the transaction, in the form, for example, of a file? A “distant” relative of Symbol, called NXT, had such functionality. Someone can tell - is there such a functional or not?
Question 2: Perhaps it was not very attentive, but I couldn’t find the answer to the question - was it possible to create a “pending” and “conditional” transaction, which, for example, would be executed after a specified time, under certain conditions?
