Question: Plot just one y label in gtrellis

I would like to plot just one y-axis label for each different track instead one for each chromosome in gtrellis package (In the manual example exemplified below the title "density" is repeated several times). I tried to modify the track_ylab parameter but it don't allows to specify which tracks must be named. There is any idea how to perform that? 

gene = readRDS(system.file("extdata", "gencode_v19_protein_coding_genes.rds", package = "gtrellis"))
gene_density = genomicDensity(gene)

gtrellis_layout(byrow = FALSE, n_track = 2, ncol = 4, 
                add_ideogram_track = TRUE, add_name_track = TRUE,
                track_ylim = c(0, max(gene_density[[4]]), 0, 1), track_axis = c(TRUE, FALSE),
                track_height = unit.c(unit(1, "null"), unit(4, "mm")),
                track_ylab = c("density", ""))

add_lines_track(gene_density, gene_density[[4]])

col_fun = circlize::colorRamp2(seq(0, max(gene_density[[4]]), length = 11), 
                               rev(brewer.pal(11, "RdYlBu")))
add_heatmap_track(gene_density, gene_density[[4]], fill = col_fun)
