Predict multiple spans/answers from same tweet

[mayankagrawal93]

I have a dataset which contains multiple indices (or spans) as output. Example : If tweet is "Getting bored of walking up and down the stairs. Dont want to do it again!" and sentiment is negative, the answer given is : "getting bored of walking ; dont want to do it again".
Here there are two spans extracted from same tweet which correctly points to negative sentiment and both of them are needed as output (not any one). I want to finetune the model in this way that it is able to extract both the spans separated by a token.
But I could not find any [SEP] token or any such similar token used by T5 in output.
Can I use EOS token after each phrase like "getting bored of walking </s> dont want to do it again </s>" ?
