SPIP/ Poetry

Hello,

I wonder to know if there is a solution for publishing poetry. Some poems are written like stairs:
Poem , poem, poem poem /line 1
Poem, poem, poem, poem/ line 2
Poem, poem, poem, poem/ Line 3
Poem, poem, poem, poem/ line 4
Poem, poem, poem, poem/ line 5
But SPIP brings all lines in one row like this:

Poem , poem, poem poem /line 1
Poem, poem, poem, poem/ line 2
Poem, poem, poem, poem/ Line 3
Poem, poem, poem, poem/ line 4
Poem, poem, poem, poem/ line 5

Is there any solution to publish poem line the first example (stairs)?
Thank you
Kamran

PS: SPIP quotations for poetry doesn’t make any sense:
