I used to plink 3k with fierce for that link, but…then I found out people frown upon using macros, so I stopped using those buttons altogether. I had to learn some actual piano techniques to do some of the EX legs combo’s that I originally learned by sliding to the 3k button too. So I don’t bother trying that particular link in actual play anymore. I can land it with just raw timing maybe 40% in training, but I don’t find it a necessity for actual play.
To answer your question though, yes, it is possible.
