So I want to reference to several sections in the eurocode without a massive bibliography. Today I'm creating a new @standard for every section in a standary that I need to reference which of course generates i.e 15 references in the bibliography.

Example

As described in [1] and [2] the choise of parametes in [3]...

BIBLIOGRAPHY

[1] SS-EN 1992-1-1 eurocode section 4.5.6.7

[2] SS-EN 1992-1-1 eurocode section 4.5.6.8

[3] SS-EN 1992-1-1 eurocode section 4.5.6.9

This is what I would like to achieve:

Example

As described in [1a] and [1b] the chose of parametes in [1c]...

BIBLIOGRAPHY

[1] SS-EN 1992-1-1 eurocode

    (a) section 4.5.6.7

    (b) section 4.5.6.8

    (c) section 4.5.6.9

Is there a nice way?

Welcome to TeX.SE!

Facing a very similar problem some time ago i modified the @set handling of biblatex with the highly appreciated assistance of moewe to get the following result:

Adapting the answer mentioned in my previous comment using the the solution of this question and the main part of this answer to your needs you can use the following:
